RAIL-SUPPORT FOR ELEVATED ROADS.

SPECIFICATION forming part of Letters Patent No. 398,023, dated February 19, 1889. Application filed November 3, 1887. Serial No. 254,141. (No model.)

To all whom, it may concern.-

Be it known that I, FRANCIS A. BARTHOLO- MEW, a citizen of the United States, and a resident of Bloomfield, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Rail-Supports for Elevated Roads, of which the following is a specification.

The object of my invention is to provide a simple and strong device to take the place of the ordinary stringers for supporting the rails upon an elevateclwrailway structure.

The improvement comprises a T-beam or other beam having ahorizontal upper flange, the edges of the said flange being turned up so as to form a groove or recess of suitable width to receive snugly the foot of the rail. A piece of wood or other material suitable to deaden the noise and act as a comparatively soft bed is interposed between the rail foot and the bottom of the said recess or groove, and the rail is secured in the recess and to the said beam, preferably bybolts passing through the rail-flange and the horizontal flange of the beam.

The invention will be hereinafter fully described, and specifically pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 represents a top View of a portion of a so-called saddle-bag road or centerrail elevated railroad embodying my present improvement. Fig. 2 is a cross-section of the same taken on the line i) o. of Fig. 1 and seen in the direction of the arrow. Fig. 3 is a detail cross-section on the line mm of a stringerbeam and rail in position thereon, the view being drawn to a larger scale than in the other figures. Fig. 4; is a cross-section of a portion of an ordinary double-track elevated road and showing one of the tracks without center rail, the rails being supported on stringer-beams, according to my present improvement, and the stringer beams being braced to the truss or tie-beam in a modified manner from that shown in Figs. 1 and 2.

A is the center rail, and a the ordinary side rails.

13 is the cross-beam upon which the stringers for the rails are placed.

0 is an iron beam, preferably a -T-beam,

which I use as a stringer for supporting the rail. For the side rails of a center-rail elevated road and an ordinary two-railed track the beam 0 is provided with a bottom flange, c, by which it is bolted to the cross-beams B.

For the elevated center rail the bottom flange, c, is dispensed with, and the vertical supporting-plates F and inclined braces G, by which the center rail is supported vertically and laterally upon the cross-beams B, are secured or bolted to the web or stem of the beam 0, as shown in Fig. 2. Angle-braces f connect the inclined braces G with the webs of the side stringers, O, for lateral support, one end of each brace f being secured to the web of the beam and theother end to the inclined brace G.

Whatever be the shape of cross-section of the beam Othat is, with or without bottom flange, c, or with one or more webs-4t is provided with the head or top flange, c, the edges d of which are turned up, as shown in Fig. 3, so as to form between them a continuous or intermittent groove or recess, H, in which the foot 1) of the rail to is supported, a bed, D, preferably of wood, being placed in the recess underneath the foot b. The rail is then secured to the stringer-beam 0, preferably by bolts E passing through the rail-foot b and the head or top flange, 0, suitable washers or bosses, e, on the rail-foot and the head a forming even surfaces for contact with the head and nuts of the said bolts E. As will readily be seen, this construction is extremely simple and very substantial. Fhen the beams O are used for an ordinary two-railed track, as in Fig. 4, they are steadied against lateral deflection by inclined braces g in the same manner as the stringer of the center rail, A, is supported in Fig. 2, the webs of the beams 0 serving as vertical support instead of the uprights F.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a rail-support for elevated roads, the combination of a stringer-beam having the edges d of its top flange, 0, turned up, forming between them a groove or recess, H, with the rail at, having foot I) confined within the said recess, a bed, D, being interposed between the rail foot and the bottom of the recess, and the rail-foot b and top flange, (1-, being secured together, substantially as hereinbefore set forth.

2. As a rail-support for elevated railroads, a stringer consisting of a W6l)-bGL111, C, having bottom flange, c, resting on the structure, and head or top flange, 0, provided with a continuous groove 01: recess, H, for the reception of the rail-foot, substantially as specified.

3. In a center rail elevated railroad, the combination of the central and side stringers, 0, consisting of T-beanis provided with recesses or grooves II for the reception of the rail-foot, the side stringers having bottom flange, a, with the supporting cross-beams ll and uprights F, and with the inclined braces G, bolted to the Web of the central stringer, and the braces f, coi'ineeting the said inclined braces to the Webs of the side-rail stringers, substantially as hereinbefore set forth.

In testimony thatl claim the foregoin gas my invention I have signed my name, in presence of. two witnesses, this 1st day of November, 1887.
